Official Sears cooktop parts

Common Sears cooktop parts that need to be replaced

• Surface element switch. On electric cooktops, the surface element switch provides power to the heating element. If this part is faulty or broken, the heating element may not reach the proper temperature or even work at all. Replace the surface element switch if it doesn't work properly.
• Electronic control board. Many cooktops have an electronic control board that controls the burners. If the display on your cooktop stops working, the failure is often caused by the electronic control board. A control board failure can also keep burners from heating. When burners don't heat or the display doesn't work, unplug the cooktop and check the wiring connections on the electronic control board because loose wires can also cause these failures. If wire connections are okay, you may need to replace the control board to fix display problems or burner failures.
• Pressure regulator. The gas supply line for the cooktop connects directly to the pressure regulator. The pressure regulator is a mechanical device that reduces the incoming gas pressure to a safe and constant level for the cooktop burners. Replace the pressure regulator if it doesn't control gas pressure properly.
• Radiant surface element. The radiant surface element is mounted on the bottom of a ceramic glass cooktop and provides heat for that area of the cooktop. It's controlled by a surface element switch (also called a surface burner switch or infinite burner switch). The radiant surface element has a limit switch that shuts off the element to protect the ceramic glass cooktop from overheating. Replace the radiant surface element if it doesn't heat when it receives current from the surface element switch.
• Spark module. The spark module receives signals from the burner switches. When a burner control knob is in the Lite position, the spark module provides voltage to the burner igniter electrodes and lights the surface gas burner. Replace the spark module if it doesn't send voltage to the igniter electrodes to light the burners.

How to troubleshoot your Sears gas cooktop when burners aren't heating properly

When all gas burner flames are weak on the cooktop, check the gas supply shut-off valve to make sure it’s fully open. If the shut-off valve is fully open and all burner flames are weak, you may need to have your gas supplier check the gas supply pressure. If gas supply pressure is okay, a failed pressure regulator on the cooktop may be restricting flow to the burners.

If a single burner isn’t heating properly, check the burner head for a spill and clean the burner head if it’s clogged.
